License agreement | Revision History
Make use of AutoCAD Architecture
or AutoCAD MEP more fully in your BIM
process. Property Set values
can automatically be updated
back and forth to one or many
If you make changes to the Extended Data values within a Property Set they can be
synchronized back to the external database. Any Property in a Property Set
Definition can be exported and all editable Properties can be imported.
ACA_db will improve the BIM
process and experience and will
improve quality of your data and
remove redundancy and conflicts

Both 32-bit and 64-bit is supported.
Any database like Access (MDB or .accdb) or SQL Server that can be connected with
dbConnect within AutoCAD is supported. Other examples are
SQL Server Express, Oracle,
ODBC, etc. AutoCAD 64-bit does only support Access 2010/2013 64-bit or the free
Microsoft Office 12.0 Access Database Engine OLE DB Provider/Microsoft

Excel is not supported as it is not a real database.
If you run 64bit AutoCAD you cannot have 32bit Office installed and also
connect to MS Access database.
Any operating system that can run the above is supported

2010-2012) or JTB.AcaDbXMgd_19.dll (for 2013)
- ACA_db_samples_2007.dwg or ACA_db_samples_2010.dwg or or
- ACA_db_license.txt (sent by email from JTB World upon request)
- Place the DLL file in a single local folder.
For example C:\Program
Files\JTB World\ACA_db .
- Place also the license file ACA_db_license.txt in the same
- ACA_db_samples.UDL should be placed in the Data Links folder.
The location is found easiest by using the
command OPTIONS and Files>Data Sources Location
- Place the MDB in a folder with read/write access.
The DLL needs to be loaded by your AutoCAD application and that can
be done in different ways. Use one of the following options.
- Use the command NETLOAD and select the DLL. This loads the
command in the current session only.
- Create a menu command, toolbar button, ribbon button or palette tool using CUI and
force load it before running the command.
Macro or Command string:
^c^c(command "netload" "C:/Program Files/JTB World/ACA_db/JTB.AcaDbXMgd_18.dll")
- Use one of the AutoLoad...reg files that can be provided. Double click on the file and accept
to merge to the registry. This will make sure that the commands
available whenever you run AutoCAD.
- Add the row below to your acad.lsp file so it loads automatically when
(command "netload" "C:/Program Files/JTB World/ACA_db/JTB.AcaDbXMgd_18.dll")
Prepare the database that holds information on what
properties to synchronize and where. See ACA_DB-UserManual.pdf on how
this is achieved.
Make sure there is an UDL file (data source) that points
out the location of the main database.
In the CAD program use ACADBSETTINGS command to specify
what data source to use as the main database.
Run the ACADBMAKE command to make new/existing drawing
possible to sync.
Now use either of the commands ACADBOUT or ACADBIN to
sync information into CAD or out from CAD.
The command line will show full details on if there are
any problems and what data has been synchronized.
Some further details.
- Property set data type and database data type must be compatible.
- A PSD must be linked to a single table.
- An object must not have 2 or more records linked from same db link.
- An object must not have 2 or more records linked from different db
links referencing same table.
- All automatic properties are considered as read-only. Such
properties can sync to database but cannot sync from database.
- All automatic properties are considered as
read-only. Such properties can sync to database but cannot sync from

click on Unblock.
